IMPROVEMENT IN VALVES FOR THE WASTE-PIPES OF SINKS.

Specification forming part of Letters Patent No. 143,883, dated October21, 1873 application filed April 25, 1873.

To all whom it may concern:

Be it known that 1, JOHN OniLooTT, of

Brooklyn, in the county of Kings and State of New York, have invented anImproved Valve for the Waste-Pipes of Sinks and other a packing of softmaterial, and a central stud or pin, and a nut applied thereto, wherebya simple valve possessing the desired requisites is obtained.

In the accompanying drawing, Figure 1 is a top view of my improved valveand its seat. Fig. 2 is a view of the seat, the valve being removed; andFig. 3 is a transverse section through the valve when in place.

Similar letters of reference indicate corresponding parts in all thefigures.

A is the socket which contains thevalveseat. It is of cylindricalform,and at the upper edge is furnished with a flange, by which it is securedto the sink or other article to which it is to be applied. The valveitself, B, is disk-shaped, and fits within the socket. It is of theoscillating kind, and is perforated on opposite sides with a series ofholes, z t, arranged to form segments of a circle. The seat 8 of thevalve is composed of two segments of a circle perforated to correspondwith the perforations in the valve. AlOllJld. about this seat is apacking, O, of india-rubber, lead, or other soft material, whichprojects up slightly above the valve-seat, and serves to close theperforations in the valve when they are turned over it. A stud or pin,-P, extends up through the middle of the socket concentrically with thetwo segments composing the valve-seat, and a nut, N, is applied to theend of this pin outside the valve. Handles a a are provided on the valveto facilitate its manipulation, and a stop-pin, b, is arranged so as toplay between two pins on the flange of the socket, and limit the motionof the valve, so that it can only turn so as to bring the perforationsin the valve in line with those in the valveseat, or else so as to bringthe perforated portion of the valve over the rubber packing. When thevalve is turned to bring the holes in the valve opposite those in itsseat, the liquid matter is allowed to drain from the sink; but, when thevalve is reversely turned, its body is over the perforations in thevalve-seat, and its ownperforations are brought over the packing, sothat the mouth of the drain-pipe is absolutely closed, and all noisomesmells issuing from the drain occlude What I claim as my invention is--The oscillating valve B, perforated as described, its perforatedsegmental seat 8, the packing O, the central pin or stud P, and the nutN, all combined and-organized substantially as described, for thepurpose set forth. 7
